Problems solved by technology

[0003] However, the existing air defense doors are all designed to open sideways, which have poor resistance to lateral impact in an emergency, resulting in poor safety. In addition, the sideway opening method is easy to fail to close in an emergency. To further improve safety in emergency situations, for this reason, we propose a steel structure air defense door to solve the above problems

Embodiment 1

[0028] refer to Figure 1-3 As shown, it is a steel structure civil air defense door in a preferred embodiment of the present invention, including a structure cabin 1 and a base 2, the structure cabin 1 is a frame of a concrete structure, and a groove is provided in the middle for placing the base 2 to carry out For the operation of lifting, a slide groove 3 is arranged inside the structure cabin 1, a slide groove 8 is arranged inside the structure cabin 1, a support frame 7 is slidably installed in the slide groove 8, and a support frame 7 is fixedly installed under the support frame 7 The door body 4, the middle part of the door body 4 is provided with a reinforcing rib 15, and the reinforcing rib 15 adopts an aluminum alloy structure, which has good mechanical structural strength. The middle part of the door body 4 is provided with a perspective mirror 16, and the perspective mirror 16 It is made of tempered glass, and when the civil air defense door is closed, the situatio...

Embodiment 2

[0032] Compared with Example 1, there are following differences, such as Figure 5 As shown, the right side of the rotating shaft 13 is provided with a crank handle 21, and the rotating shaft 13 is a Z-shaped rotating shaft. The stripes are used for manual use in emergency situations, and can realize lifting and lowering of the door body 4 by hand, with stronger adaptability, when unexpected situations occur.

[0033] The specific implementation process: turn the handle 21, drive the rotating shaft 13 and the gear 12 to rotate through the speed change of the gearbox 20, drive the rack 11 to move up and down through the rotation of the gear 12, and drive the door body 4 as a whole through the rack 11. The lifting is guided by the structural design of the support frame 7 and the chute 8, and the stability of the structure is improved to realize the vertical lifting of the door body 4. This structure can resist greater side impact force, thereby increasing the danger of the air d...

Abstract

The invention discloses a steel structure civil air defense door which comprises a structural cabin and a base. The structural cabin is internally provided with a slide-moving groove, the structural cabin is internally provided with a sliding groove, a supporting frame is slidably installed in the sliding groove, and a door body is fixedly installed under the supporting frame. A base is arranged at the bottom of the structural cabin, a limiting block is arranged inside the base, a plurality of sets of blocking blocks are arranged at the bottom of the door body, and an upper blocking block is arranged on the inner upper part of the structural cabin. According to the steel structure civil air defense door, a rotating shaft is driven to rotate by a motor, a rack is driven to move up and downby the rotation of a gear, the door body is driven to lift and lower through the gear, and the structure design of the supporting frame and the sliding groove is used for guiding to achieve the vertical lifting and lowering of the door body; the structure can resist greater side impact, thereby enhancing the hazard protection capability of the civil air defense door; and in addition, the verticallifting structure can use the gravity of the door body to assist in the descent, closing is more easier, and the safety is further improved in emergency situations.

Description

technical field [0001] The invention relates to the field of civil defense doors, in particular to a steel structure civil defense door. Background technique [0002] Civil defense is also called civil defense. Civil defense is an international common term. It is an activity in which the government mobilizes and organizes the masses, adopts anti-airstrike, disaster relief measures, implements rescue operations, and prevents and mitigates disasters. The civil air defense door belongs to the civil defense protective equipment. [0003] However, the existing air defense doors are all designed to open sideways, which have poor resistance to lateral impact in an emergency, resulting in poor safety. In addition, the sideway opening method is easy to fail to close in an emergency. To further improve safety in emergency situations, for this reason, we propose a steel structure air defense door to solve the above problems. Contents of the invention [0004] In order to overcome t...
